Software testing Technology (III.)--UI testing using causality Diagram method

Target Program

Add two identical input boxes to the previous one

Introduction to How to use

• Causality Diagram method

In introduction to software testing by Paul, the coverage criteria for software testing are divided into four categories, logical expressions,syntactic Descriptions,graphs,input Domain characterizations, as far as I can see, equivalence class partitioning belongs to input domain characterizations, control flow and data flow test belong to graphs, and causality diagram method belongs to logical Expressions It finds the cause (input condition) and the fruit (output or program state change) from the description of the program specification written in natural language, and can be converted to a decision table by causality diagram.

• Steps

list cause and effect

draw a causal diagram

judging form According to the cause and effect drawing

If there are too many variables, you can simplify the decision table before you design the test case

Causes and results

Reason Number	Content
C1	The first input box is not entered
C2	The second input box is not entered
C3	The third input box is not entered
B1	The first input box entered an error
B2	The second input box entered an error
B3	The third input box entered an error
Result number	Output action	Demand
Ef1	An error message appears after the first input box	C1 or B1
Ef2	An error message appears after the second input box	C2 or B2
Ef3	An error message appears after the third input box	C3 or B3
Ef4	Show "Success"	Three input boxes are entered correctly
